    To people confused about the focal length of the concave mirror, I did some research.
    It's just a convention and either way can work - you just need to be consistent, whichever you choose.
    From my research, the most used convention is the focal length of a concave mirror is POSITIVE. (same convention with other converging devices such as convex lens)
    Which I would stick to, since this video went with that convention, and changing things over will cause unnecessary confusion.

    The 2 incident rays:
    Obj to mirror to focal ( not parallel to axis plane)
    Obj to focal to mirror ( parallel to axis plane)
    Special case (convexed lens) - obj to mirror refract to center whereby center distance to mirror is radius thus focal/focusing point distance to mirror is r/2
    Actual converge/intersect is Real i
    fake converge formed from actual divergence is Virtual image (so to say, diverge on front side && converge back side && image behind mirror)

    Hey great video but I noticed a mistake at 13:48. If you have an object placed between f and C, the reflected image will be located beyond C (as in di > 2f).
    I checked my math with the sample of f=8cm, do = 12 cm, ho = 4 cm. In this situation, I found that C =16 cm and the calculated di = 24 cm so therefore di > C.
